Speculators ramp up £2bn bet against sterling ahead of Chancellor's Budget
CFTC data shows net short positions on the pound rise to levels not seen since the 2022 mini‑Budget turmoil as markets brace for tax rises and fiscal strain
Traders have increased net short positions against the British pound to roughly 33,000 contracts, equivalent to about £2 billion, according to the latest data from the US Commodity Futures Trading Commission (CFTC), in a sign of renewed market concern about the UK's fiscal outlook ahead of the autumn Budget.
The rise in 'sell' futures positions reverses a positive trend for sterling earlier this year and comes as Chancellor Rachel Reeves prepares a November Budget in which she is widely expected to approve further tax increases to close a gap in the public finances that advisers have estimated could be up to £50 billion a year.
The CFTC tracks how traders are positioned in futures contracts, a commonly used gauge of speculative sentiment. Market strategists say growing net short positions indicate traders expect the UK's fiscal challenges to weigh on sterling in the months ahead. "Negative bets on sterling indicate that speculators are betting that the UK’s fiscal woes will be the dominant factor for the pound in the months ahead," said Jane Foley, head of foreign exchange strategy at Rabobank.
While notable, the current level of short positions remains well below the peak of roughly 80,000 contracts recorded in 2022, when the so‑called mini‑Budget and unfunded tax cuts unsettled markets and precipitated a sharp fall in sterling. Analysts say the comparison is useful for measuring sentiment, but that the present position count does not approach the scale seen during that crisis.
The resurgence in short positions arrives amid heightened scrutiny of UK public finances and renewed debate over the mix of tax rises and spending adjustments the government will employ to stabilise borrowing. Traders and investors often react to fiscal uncertainty by hedging or speculating in currency markets, which can put further pressure on exchange rates and complicate official plans to manage debt servicing costs.
Market participants note that futures positioning is only one measure of sentiment and that foreign exchange moves will also reflect interest rate differentials, global risk appetite, and incoming UK economic data between now and the Budget. Nonetheless, the CFTC figures are watched closely because they quantify how large and leveraged market participants are betting on currency moves.
Treasury officials have not commented on the CFTC data. The Chancellor's office has previously said that any fiscal decisions will aim to restore sustainable public finances while supporting growth. The balance between tax rises and other measures will be central to market assessments of the UK's economic trajectory.
Analysts caution that positioning can shift quickly as political developments, economic releases and central bank actions unfold. The November Budget deadline gives markets time to reassess risks, but the recent increase in net short positions underscores that at least some investors are betting sterling will come under renewed downward pressure if fiscal tightening is perceived as insufficient or if tax changes are judged to harm growth.
The coming weeks are likely to see close attention paid to UK fiscal announcements, consumer and business activity indicators, and Bank of England commentary, all of which will influence whether the current build‑up of short bets is unwound or intensifies ahead of the Chancellor's fiscal update.
